I don't think you are correct for single-core performance.

A20 Pro scores around 4725 at 8.9w. Geekerwan's review showed that the iPhone 18 pro could dissipate as much as 6.4w during long gaming tests. Cutting power by 50% likely still keeps around 80% of the clockspeed.

As 9950x scores around 3400-3450 in geekbench, or around 28% slower.

There's a very good chance that the iPhone single thread performance is genuinely faster even during sustained loads.
